Hi,
You didn't provide a reproducible example. If your dataset is something like
this:
set.seed(495)
DataSeries <- data.frame(Date=seq(as.Date("2001-01-01"),by="1 day",
length.out=20), A= sample(10,20,replace=TRUE), B= rnorm(20))
###Using your codes:
Matrix_New1 <-
cbind(as.list(DataSeries[,"Date"]),as.list(DataSeries[,"A"]),colnames(DataSeries)[2])
Matrix_New2 <-
cbind(as.list(DataSeries[,"Date"]),as.list(DataSeries[,"B"]),colnames(DataSeries)[3])
str(Matrix_New1)
#List of 60
str(Matrix_New2)
#List of 60
Matrix_Complete<- rbind(Matrix_New1,Matrix_New2)
str(Matrix_Complete)
#List of 120
Col_Names_MC<-c("X","Y", "Z")
colnames(Matrix_Complete)<-Col_Names_MC
library(lattice)
Plot_AB<-xyplot(Y~ X, data =Matrix_Complete, type =c("l"), groups=Z,
as.table=TRUE, main="Development over time")
#Error in eval(expr, envir, enclos) : object 'Z' not found
#You could try:
library(reshape2)
DataSeriesM <- setNames(melt(DataSeries,id.var="Date"),LETTERS[c(24,26,25)])
xyplot(Y~X,data=DataSeriesM,type="l",groups=Z,as.table=TRUE,main="Development
over time")
#for a numeric X axis
xyplot(Y~as.numeric(X),data=DataSeriesM,type="l",groups=Z,as.table=TRUE,main="Development
over time")
# with legends
xyplot(Y~as.numeric(X),xlab="X",data=DataSeriesM,type="l",groups=Z,as.table=TRUE,main="Development
over time",auto.key=list(x=.85, y=.95, border=TRUE,lines=TRUE))
Hope it helps.
A.K.
Hi everbody, I have the following error message occuring when I run my code:
"Error in eval(expr, envir, enclos) : object 'Series' not found" The code I am
using is the following: Matrix_New1 <-
cbind(as.list(DataSeries[,"Date"]),as.list(DataSeries[,"A"]),colnames(DataSeries)[2]
)
Matrix_New2 <-
cbind(as.list(DataSeries[,"Date"]),as.list(DataSeries[,"B"]),colnames(DataSeries)[3]
) #whereas first and second columns should be numbers, third column is "A" and
"B" respectively Matrix_Complete<- rbind(Matrix_New1,Matrix_New2)
Col_Names_MC<-c("X","Y", "Z")
colnames(Matrix_Complete)<-Col_Names_MC Plot_AB<-xyplot(Y~ X, data
=Matrix_Complete, type =c("l"), groups=Z, as.table=TRUE, main="Development over
time") print(Plot_AB) Can you explain me why this way of creating a plot is not
working and what I Need to Change in order to be able to plot it?
